Abstract: A spring plate, especially for a MacPherson strut unit, having an axial support surface for the final turn of a helical spring. The helical spring is centered by radial centering surfaces in the area of the circumferential contour of the final turn. The centering surface is divided into individual, partial centering surfaces, which come to rest against the circumferential contour of the helical spring.

Abstract: A vibration damper including a cylinder with a cylinder-side connection member. The at least one mounted component is fastened to the cylinder by a material bond. The cylinder and the mounted component are made of plastic. The mounted component and/or the cylinder are based on at least one ready-prepared semi-finished product that forms the surface of the vibration damper on at least one body side in the final state. Plastic supplemental volume fractions determine the finished body contour.

Abstract: A plastic spring having a corrugated tubular body with connection surfaces at its ends for transmitting force between two structural component parts which are movable relative to one another. A connection surface of the plastic spring is constructed as a tubular body which engages in a cup element of one of the supporting structural component parts. The cup element can be filled with a displacement mass, and the tubular body accordingly carries out a displacing movement within the cup element for axially adjusting the preloading of the plastic spring.

Abstract: A supporting tube for a vibration damper including an axial supporting surface on which rests an outer cylinder of the vibration damper. A fixing cap which holds a second axial supporting surface for securing the cylinder against loading in the opposing direction. The fixing cap is connected to the supporting tube by positive engagement, and separate locking elements for both parts are arranged between the fixing cap and the supporting tube, which locking elements position the outer cylinder relative to the supporting tube.

Abstract: Presented is a vibration damper that includes an outer cylinder with a lateral surface, a pin-shaped fastening element that includes a stop surface, and a mounting coupled to the lateral surface. The mounting defines a through-hole that is configured to receive the pin-shaped fastening element and extends circumferentially with respect to the lateral surface. The mounting includes a formation that extends in a radial direction with respect to the cylinder. The formation cooperates with the outer cylinder to form a socket for the stop surface. The stop surface rests against the mounting in an axial direction of the pin-shaped fastening element.

Abstract: A cylinder having an attachment on which a component having an internal taper surface is fixed, wherein in a positive anti-turning connection is in effect between the cylinder, and the taper connection has at least two regions in the circumferential direction having a smaller and a larger taper angle.

Abstract: Presented is a vibration damper that includes an outer cylinder that includes a lateral surface, a pin-shaped fastening element that includes a stop surface, and a mounting coupled to the lateral surface. The mounting defines a through-hole that is configured to receive the pin-shaped fastening means and extends circumferentially with respect to the lateral surface. The mounting includes a formation that extends in a radial direction with respect to the cylinder. The formation cooperates with the outer cylinder to form a socket for the stop surface. The stop surface rests against the mounting in an axial direction of the pin-shaped fastening element.

Abstract: A spring strut tube assembly having an outer container tube, or tubular member and a spring plate. One end of the tube can be closed by a bottom part and the other end of the tube can comprise an aperture and a slid-on spring plate. The tubular member can be produced from a flexibly rolled flat material whose wall thickness is variable in the longitudinal direction. The tube is formed in a direction transverse to the longitudinal direction, and can be welded in the longitudinal direction.

Abstract: Spring strut comprising a cylinder, with respect to which the axial position of a spring collar can be adjusted, where the spring collar has a sleeve section, by which it is connected to the cylinder, where, on the cylinder side, a chamber is provided, which is at least partially filled with a curable material, where the sleeve section is in contact with the curable material, which, when in the solid state, transmits a supporting force from the cylinder to the spring collar, where the chamber has at least one isolating sleeve with a radial guide surface, by which the sleeve is in contact with the sleeve section of the spring collar.

Abstract: A suspension strut including a piston rod extending from a cylinder, a connection bearing for connecting the piston rod to a vehicle body, a spring loading the cylinder away from the connection bearing, and a spring plate supporting the spring axially with respect to the connection bearing. A first bearing enables relative rotational movement between the spring plate and the connection bearing, and a second bearing enables relative rotational movement between the connection bearing and a stop buffer arranged between the connection bearing and the cylinder.

Abstract: Suspension strut unit comprising a cylinder, with respect to which the axial position of a spring collar can be adjusted, where the spring collar has a sleeve section which is received in a chamber provided on the outside of the cylinder. The chamber is at least partially filled with a curable material, and the sleeve section is in contact with the curable material, which, in the solid state, transmits a supporting force from the cylinder to the spring collar. The chamber has at least one isolating sleeve with a radial guide surface, by which the sleeve is in contact with the sleeve section of the spring collar.

Abstract: Spring strut unit, comprising a cylinder, with respect to which a spring plate can be shifted axially for the purpose of adjusting the position of the cylinder. The spring plate has a sleeve section, which establishes the connection to the cylinder, where, on the cylinder side of the unit, a chamber is provided, which is at least partially filled with initially formable material, where the sleeve section is in contact with the initially formable material, which, when in the solidified state, transmits supporting forces from the cylinder to the spring plate. In the path of force transmission from the spring plate to the cylinder, a rotation-proof connection is provided, which determines the position of the spring plate with respect to the cylinder.
